Model: PV1800 VHM series  2KW-5.5KW

This is a multi-function inverter/charger, combining functions of inverter, MPPT50A/80A solar charger and battery charger to offer uninterruptible power support with portable size. Its comprehensive LCD display offers user-configurable and easy-accessible button operation such as battery charging current, AC/solar charger priority, and acceptable input voltage based on different applications.


Main Advantages of PV1800 VHM series:

• Rated power 2KW to 5.5KW
• Pure sine wave output
• Smart LCD setting (Working modes, Charge Current, Charge Voltage, etc).
• Bult in MPPT 80A solar charge controller
• Combining solar system, AC utility, and battery power source to supply continuous power
• Overload, short circuit and Deep discharge protection
• Cold start function
• Support USB, RS485 monitoring function with free CD
• WIFI remote monitoring (optional)
• Compatible to generator
• 4KW-5.5KW support parallel function(optional)

Connection in Solar system& connection in Parallel 

Pure Sine Wave Output: The electrical waveform output of PV1800VPM is a pure sine wave, which has the same quality as utility and/or domestic power. This type of waveform is suitable for most all electrical devices, appliances and tools. This pure sine wave unit provides more capabilities than modified sine wave inverters, because it is a cleaner form of power. The pure sine wave also effectively reduces the noise produced while using appliances.

Wifi communication: you can download this app on your cellphone and monitor the whole system, you will know know how much electricity the system generate and sell to utility

4-5.5KW Parallel function: Customer can use 2pcs or 3 pcs inverters to expand the system capacity. Maximum 3pcs parallel to single phase or three phase.Parallel kit picture as below:

6-Charging algorithm: 3-Step (Flooded Battery, AGM/Gel/Lithium Battery),4-Step(LI)

Monitoring system: With USB can connect with computer monitoring the working stage and the data of PV, AC and battery. LCD setting is also available in computer.

Utility-Tie state: PV energy is charger into the battery and utility provide power to the AC load

Bypass state: Error are caused by inside circuit error or external reasons such as over temperature, output short circuited and so on.

Off-Grid state: The inverter will provide output power from battery and PV power
